Receivers and Audio Components

I have 2 ?'s for you . . . .

On some FM radio stations there is static (and it's set to the exact station), and I just need to move the antenna a bit, any suggestions on how to permanently make the static go away???

Next ?? . . . . this is a 5 CD playing machine, can I push a button somewhere to play selections from all 5 at a time without just playing the whole CD a song at a time???    On my old 3 Cd player I could push "random", does this have that option???

A friend of my grandfather gave him a set of Sony floor speakers with two rear speakers.  He didn't get a owners manual.  Since my grandfather is giving the system to me, I was curious about the specifications of the system.  When I looked on the internet to find it, I could not find the specs on them.  It is like they don't exist.  on the back of the floor speakers, the model number is SA-VA3A.  any help would be appreciated. thank you

All I get is "fuzz" or static on the FM tuner. It's a Pioneer VSX-D603S.  We tried attaching the FM antenna, but still nothing.  Do you know what's the problem!
